guitarchordschemes – Guitar Chord and Scale Tablatures

This pack­age pro­vides two com­mands (\chord­scheme and
\scales).

With those com­mands it is pos­si­ble to draw schematic di­a­grams of
gui­tar chord tab­la­tures and scale tab­la­tures. Both com­mands know
a range of op­tions that al­low wide cus­tomiza­tion of the out­put.
